Ozette applies artificial intelligence to immune monitoring to gain greater insight into a cancer patient’s immune system. Beyond informing treatment decisions, the technology can guide drug and diagnostic development.
QubitTech has built an ecosystem to boost investment returns and create stable passive income.
We spoke with the leader of the World Health Organization’s recent mission to China to probe the origins of the #COVID19 pandemic. Here’s what we learned:
Lab accident hypothesis, while “extremely unlikely,” has not been ruled out, Peter Ben Embarek says after returning from 4-week investigation.
“Figures published in 2011 suggest that, in Australia, producing wheat and other grains results in: at least 25 times more sentient animals being killed per kilogram of useable protein more environmental damage, and a great deal more animal cruelty than does farming red meat. How is this possible? Agriculture to produce wheat, rice and pulses requires clear-felling native vegetation. That act alone results in the deaths of thousands of Australian animals and plants per hectare. Since Europeans arrived on this continent we have lost more than half of Australia’s unique native vegetation, mostly to increase production of monocultures of introduced species for human consumption. Most of Australia’s arable land is already in use. If more Australians want their nutritional needs to be met by plants, our arable land will need to be even more intensely farmed. This will require a net increase in the use of fertilisers, herbicides, pesticides and other threats to biodiversity and environmental health. Or, if existing laws are changed, more native vegetation could be cleared for agriculture (an area the size of Victoria plus Tasmania would be needed to produce the additional amount of plant-based food required). Most cattle slaughtered in Australia feed solely on pasture. This is usually rangelands, which constitute about 70 per cent of the continent.”
Going vegetarian, or even vegan, to minimise animal suffering and promote sustainable agriculture, actually kills more sentient animals living in vegetable crops that livestock farmed in paddocks.

A team of researchers from Johns Hopkins Medical Campus, working with medical research company 10x Genomics has used a spatial gene expression technology to further define the six-layered human dorsolateral prefrontal cortex. In their paper published in the journal Nature Neuroscience, the group describes their use of the new technology and what it allowed them to see in their study of the dorsolateral prefrontal cortex.
SpaceX completed another monster equity funding round last week, sources said, sending the valuation of Elon Musk’s company to about $74 billion.
An international team led by researchers at the Centre for Palaeogenetics in Stockholm has sequenced DNA recovered from mammoth remains that are up to 1.2 million years old. The analyses show that the Columbian mammoth that inhabited North America during the last ice age was a hybrid between the woolly mammoth and a previously unknown genetic lineage of mammoth. In addition, the study provides new insights into when and how fast mammoths became adapted to cold climate. These findings are published today (February 172021) in Nature.
Around one million years ago there were no woolly or Columbian mammoths, as they had not yet evolved. This was the time of their predecessor, the ancient steppe mammoth. Researchers have now managed to analyze the genomes from three ancient mammoths, using DNA recovered from mammoth teeth that had been buried for 0.7−1.2 million years in the Siberian permafrost.
